overset+7MnO4- arrow Mn2+ change 5 arrow overset+6MnO42- change 1 arrow overset+4MnO2 change 3 arrow overset+3Mn2O3 change 4

Q. $M n O_{4}^{-}$ is a good oxidising agent in different medium changing to
$M n O_{4}^{-} ⟶ M n^{2 +}$
$⟶ M n O_{4}^{2 -}$
$⟶ M n O_{2}$
$⟶ M n_{2} O_{3}$
Changes in oxidation number respectively are :

1,3,4,5

5,4,3,2

5,1,3,4

2,6,4,3

$M n + 7 O_{4}^{-} \to M n^{2 +}$ change 5

$\to M n + 6 O_{4}^{2 -}$ change 1

$\to M n + 4 O_{2}$ change 3

$\to M n_{2} + 3 O_{3}$ change 4
